Product introduction:
1. Use width voltage LM393 comparator;
2. Work voltage 3.3V-5V;
3. The output of the comparator, the signal is clean, the waveform is good, the driver capacity is strong, more than 15mA;
4. Power distribution position regulating sensitivity;
5. Output form: Digital switching output (0 and 1) and analog AO voltage output;
6. There is a fixed bolt hole for easy installation;
7. Small board PCB size: 32mm x 14mm
8. Large plate PCB size: 50mm x 40mm

Function introduction:

Connect the 5V power supply, the power indicator light is bright, and when there is no water droplet on the inductive board, the DO output is high level, the switch indicator light is extinguished, a drop of water, the DO output is low level, the switch indicator light is on,Brush off the water droplets above and return to the high level of output.

AO simulation output can connect the amount of rain on top of the AD port of the single -chip microcomputer.

Do TTL digital output can also connect the single -chip microcomputer to detect whether there is rain.

Wiring method:
1.VCC: Plot power positive (3-5V)
2.GND: connect the power supply pole
3.Do:ttl switch signal output
4.ao: Sims signal output

Product use:
Robot kit, raindrops, rain sensors, can be used for monitoring of various weather conditions, and converted into number signal and AO output.

Package contains:
6PCS Water Sensor Rainwater Module
